Block Parameters

Channel vector

List the output channels as a vector. Up to 8 different channels can be listed. To specify the first three channels, enter

[1,2,3]

The board comes in two different versions. If you use the 4-channel version and include channels 5-8, the those outputs will not show an error, but the data will be ignored.

Range

The output range of the board is selected with jumpers on the board. Each group of 4 channels can be jumpered for the available ranges. The range you select in the Block Parameters must correspond to the range specified by the jumper settings or you will obtain unexpected results.

Reset vector

The reset vector controls the behavior of the channel at model termination. Enter a scalar or a vector that is the same length as the channel vector. If you specify a scalar value, that setting is replicated over the channel vector. If you specify a value of 1, the corresponding channel is reset to the value specified in the initial value vector. If you specify a value of 0, the channel remains at the last value attained while the model was running.

Initial value vector

The initial value vector contains the initial voltage values for the output channels. Enter a scalar or a vector that is the same length as the channel vector. If you specify a scalar value, that value is replicated as the initial value over the channel vector. The channels are set to the initial values between the time the model is downloaded and the time it is started.

Sample time

Enter the base sample time or a multiple of the base sample time (-1 means sample time is inherited).

Base address

Enter the base address of the board. This entry must correspond to the DIP switch setting on the board. For example, if the DIP switch setting is 300 (hexadecimal), enter 0x300.

    Note:   Please consult the Diamond Ruby-MM manufacturer documentation for more information on jumper settings and I/O connections.
